Some of the bizarre things I liked about the potential of this timeline also make it considered ASB (Alien Space Bats) on the wiki. Things like unrealistic randomness, alien interventions, or a bias for a particular country that defies reality can earn an ASB label.
As I've looked closer I've noticed it has four ASBs against it. Three biased (Croatia becoming a super-power, Australian aborigines having more control over their continent, and a large group of African nations uniting to wage war on a Croatian superpower during the chaos of a nuclear winter) each of which was very, very unlikely. The fourth is the technology. After two large-scale nuclear wars and the world's population being reduced to 1.5 billion I have trouble believing humanity could successfully create a Mars colony.
Be that as it may, I have decided to devote up to six months of regular additions to this timeline to see if I can reduce some of the ASB factors or at least give it an internal consistency that is entertaining, or even entertaining to the althistory work of others. There are so many things I could expand on I'm having trouble deciding what to focus on next. There are a number of wars to give details on, there is the aftermath of World War III to explore, there are the conditions and society on the Mars colonies, and numerous other topics I could expand on. Taking things slow, one or two posts a day for six months should leave me with something that ends up being pretty cool.
Now I have to see how the Map Games they have on the wiki work and consider experimenting with that. There is also their centerpiece timeline, Doomsday: 1983, which looks like it could be fun to contribute to.... just a lot of information to absorb on that one.
Check the wiki out and see what interesting things you can find.
